Dialog Introduction : JDialog « Swing « Java Tutorial

  1. A dialog can be either modal or modeless.
  2. A modal dialog blocks user input to all other windows in the same application when it is visible. You have to close a modal dialog before other windows in the same application can get focus.
  3. A modeless one does not block user input.
  4. A dialog can belong to another dialog or a frame. Or, it can stand alone like a JFrame.
class Help extends JDialog {
  Help(Frame frame, String title) {
    super(frame, title);

    try {
      JEditorPane ep = new JEditorPane("file:///" + new File("").getAbsolutePath() + "/uchelp.html");
    } catch (IOException ioe) {
      JOptionPane.showMessageDialog(frame, "Unable to install editor pane");

    setSize(200, 200);
